That is an option, but it would still have to be coded for specifically. Some projects do write separate OpenCL Nvidia and OpenCL AMD apps, but not all. Those that do have the option of being that hardware specific, which of course prevents the same OpenCL app from working on AMD or vise versa. Would also prevent the same app from working on an Nvidia GPU with only CC 3.0 or lower. Similar to the SSE instructions from Intel, if you code for SSE 2, but your CPU and compiler supports SSE 4.2, you still only get SSE 2.

Regarding the Titan though, there is a glimmer of hope afterall. New "official" specs have been released showing the Titan getting 1.3 TFLOPS FP64, however it seems the release price has climbed to $999. While 1.3 TFLOPS DP would be nice, for that price you can get a 7990 (7970 x2) and get pretty close to 2 TFLOPS. I don't understand why they're only claiming 1.3 when it should be 1.5 since this architecture has DP working at 1/3 SP which is rated at 4.5 TFLOPS. The Titan is also 10.5 inches long which is 0.5 inches shorter than the 690.

TDP is confirmed at 250W which is ~50W less than a 690. The 384-bit 6GB VRAM is clocked at 6008MHz. Base clock is 837MHz with boost at 876MHz. The Boost clock is now based on GPU temp (GPU Boost 2.0), rather than the power range of the core as it is on the 600 series. OverVoltage will also be hardware supported, but the companies that put their stickers on it (Asus, EVGA, etc) have the option of preventing you from using it if they feel like it. You can adjust the target temp of the GPU Boost (default is 80C). Increasing it will raise the Boost frequency.

The NDA on performance results will be lifted thursday.
